“If you do seen a power line down please do not go near it and call Western Power on 131351.”

“The strongest gusts so far have been 109km/h at Rottnest Island and Ocean Reef,” he said.

Severe weather warning

A severe weather warning remains in place for Perth and a large chunk of the southern half of the state, as strong winds and rain lash the coast on Saturday morning.

The latest warning from 6.30am Saturday applies to people in the Perth metropolitan area, Midwest Gascoyne, Goldfields Midlands, Great Southern, South West and Lower South West regions.

It covers an area south-west of a line from Geraldton to Paynes Find to Israelite Bay and includes people in the Perth metropolitan area, Geraldton, Dalwallinu, Jurien Bay, York, Mandurah, Bunbury, Busselton, Margaret River, Bridgetown, Albany, Katanning, Narrogin, Southern Cross, Esperance and surrounding areas.

Dangerous winds of more than 100km/h are forecast, with wind gusts of up to 125km/h. By early Saturday morning Cape Naturaliste had already experienced a wind gust of 109km/h, with Rottnest recording winds up to 98km/h.

The storm is set to bring heavy rain and the potential for flash flooding, with the Witchcliffe weather station picking up more than 50 millimetres between 1am and 5am Saturday and Bridgetown showing almost 46 millimetres between 3am and 5.30am.

Some areas of Perth had received their forecast Saturday rainfall of 30 millimetres before 7.30am.

Higher than normal tides may cause flooding of low-lying coastal areas, particularly along the west coast during Saturday morning around the time of high tide.

If your home has been badly damaged by a storm, call the SES on 132 500.

On Friday, Surf Life Saving WA general manager Chris Peck had warned people that the water wasn’t the place to be on Saturday.

Mr Peck said the message from Surf Life Saving WA was simple in the face of what could be a biggest swell for a couple of years..

“The message is, if you want to go down to the beach, stay on the dry sand and watch in awe of what’s going on out there but just don’t enter [the water],” he said.

“Patrols are finished for the seasons so obviously the lifesavers are having a well earned winter rest.

“If you’re in trouble, you’re going to be on your own tomorrow.” @abcnewsPerth how’s this for #PerthStorm damage?
